金属栅电容耦合弯曲沟道中电子波包传输的磁场不对称性
Magnetic-field asymmetry of electron wave packet transmission in bent channels capacitively coupled to a metal gate
摘要:
研究了电子波包在弯曲通道中的运动。我们证明了当电子包与金属板电容耦合时,电子包的传输几率成为磁场的非均匀函数。耦合通过非线性电势发生,该非线性电势将用于相反磁场取向的传输的不同动力学转换成散射电子感受到的不同电势。
英文摘要:
We study the electron wave packet moving through a bent channel. We demonstrate that the packet transmission probability becomes an uneven function of the magnetic field when the electron packet is capacitively coupled to a metal plate. The coupling occurs through a non-linear potential which translates a different kinetics of the transport for opposite magnetic field orientations into a different potential felt by the scattered electron.
